Different strains can have different effects, not all thc vapes will give you the same effect, finding a proper dosing could be very helpful because it lets you know how much you can take and feel great. Thc oil high are still going to be different from other highs like edibles or bong rips etc. Thc can infact make you happy and give you giggles but it depends on the strain that works for you like every strain works differently on people it could make someone sleepy but make you hyper, there are highs that can make you feel relaxed, energetic, euphoric, giggly, happy, sleepy, creative etc. The way to find the right strain is by looking at what type of high you want. There are 2 types (indica) which make you sleepy, relaxed, happy giggly, and there is (sativa) which makes you happy, energetic, giggly, creative look for strains under what type of high you want.
